IT'IESNE ASSIGNMENTS, TO CLAYTON 8c LAMBERT MANUFACTURING 00., OF DETROIT, MICHIGAN, A GQRPOBATION OF DELAWARE i FIRE POT STRUCTURE Application filed June 11, 1928.

This invention relates to fire pot structure, and has to do particularly with a combined top and burner structure and manner of assembling the same.

Heretofore it has been the practice to construct fire pots with separate burner and top structure. This has not only resulted in complicating the assembly, but such separately formed top structures have usually been subjected to intense heat from the burner structure resulting in rapid burning out or deterioration of the top structure. In an application filed December 7, 1927, Serial No. 238,264, a combined top and burner structure for iire pots is shown and claimed, which completely eliminates the objections to former fire pots, us to separate top and burner structure, in that an annular ring is provided which forms aburner as well as the top, and a deflector plate is positioned in the center whereby to project the flames inwardly and upwardly.

It is the object of the present invention to materially improve the construction shown in said application #238,264 wherein the burner structure, the central deflector plate, and the shield for the burner are so designed and arranged as to be easily assembled and maintained in assembled position by a single securing means. The direct result of this structure is that the burner member or screen and the deflector member for positioning the same may be assembled arbitrarily as to relative positions, and such parts together with the shield for the burner held together by means of a single securing means.

In the drawings:

ting the same away whereby it may be readily assembled in place.

The combined top and burner structure which forms the basis of this invention may generally be designated 1 and is preferably. annular in shape and substantially rectangular in cross section so as to provide an annular passageway for the vaporized fuel which may be conducted thereto by means of the conduit 2 and the mixing chamber 3. The fuelis preferably fed to a suitable generator tube, one end of which is shown as at 4, and this generator tube is preferably heated wherby to vaporize the fuel and to discharge the same into the mixing chamber 3. The particular design and arrangement of the generating apparatus is immaterial in the.

present invention.

The inner wall of the annular burner 1 is preferably slotted, as at 5, and a suitable annular perforate screen 6 is adapted to be positioned around the inner wall of the burner source to form the burner opening for the burner.

Screen member 6 is held in position by a circular member 7 which not only serves as a positioning means for the burner screen but also has a deflector for deflecting the flames inwardly and upwardly. This member 7 is provided with two annular members 8 and 9 which provide a space 10 for registering with the groove 5 formed in the annular burner.

The deflector member 7 is also provided with stepped supporting members 11 for receiving and positioning the melting pot. A suitable shield 12 is preferably provided with suitable openings or slots to permit the same to be inserted over the stepped members 11 and held in position over the top of the burner 1 so as to confine the flames around the sides of the melting pot.

A suitable shield 13 is fabricated, as best shown in Figs. l and 5, the slot 14 being adapted to fitaround the member 4, and the openings 15 and 16 being adapted to receive the manifold 2 and a portion of the gcnerating structure of the burner. It will thus be obvious that the shield 13 may be quickly and easily inserted in place beneath the annular burner to inclose all the generating apparatus and present a fire pot of neat appearance.

The deflector member 7 is provided with a suitable counter-sunk aperture 17 for receiving and positioning the bolt. The burner casting is preferably threaded, as at 19, to re ceive a sleeve 20, and the shield member 13 is provided with a centrally positioned aperture 21 for receiving the bolt 18.

In assembling the complete structure it will be obvious that it is only necessary to place the screen 6 in place, and arbitrarily insert the deflector and positioning member 7 screw the sleeve 20 into place, insert the shield member 13 into position whereby the end of the bolt protrudes therethrough, and then secure the entire structure in assembled relation by securing a single nut to the end of the bolt 18. In order to dismantle the structure, it will be obvious that this likewise will be very easily accomplished. V

The entire end of the burner structure may be suitably supported above fuel supply tank 26 in the standard manner, as by means of supporting and spacing bolts 23, such bolts being adapted to fit in suitable aperturesQl provided in lugs 25 which form a part of the burner casting. As will be obvious in Figs. 1 and 2, the entire generating and burner structure will be supported by these bolts 23 where by the complete burner structure may be as-v sembled as a unit above the tank or base. It

will furthermore be obvious that all the parts such as the shield 13, screen 6, and deflector 7, etc., maybe readily and quickly removed by unscrewing the nut on the bolt 18 without removing the combined top and burner structure from its normal fixed position above the fire pot base.

It will thus be seen that we have provided a novel compact structure which has not only materially simplified the burner structure design but which has made it possible to assemble the various parts of such burner structure in much less time than has heretofore been possible.

lVhat we claim is: V

1. A fire pot, comprising an annular burner structure, a flame deflector plate positioned centrally thereof, a shield positioned below the burner and a single means positioned axially of said plate, shield and burner for holding the burner, deflector plate and shield in assembled relation.

2. A fire pot, comprising an annular burnv er structure positioned above the fuel tank,

generating apparatus extending and positioned below said burner structure, a shield adapted to be freely movable around said generating structure into a position below the burner structure, and a'single means positioned axially of the burner structure and extending through the shield for holding the shield and burner structure in assembled relation.

3. A fire pot, comprising a burner structure directly supported above the fuel tank, a flame deflector member adapted to be positioned in deflecting relation to the burner, a generating apparatus positioned below the burner structure, a shield surrounding the generating apparatus and engaging the bottom of the burner, and a single means positioned axially of and adapted to maintain the burner, deflector member and shield in assembled position. 1

4.

6. A fire pot of the liquid fuel type, comprising an annular burner structure directly supported above the fuel tank, generating apparatus positioned in part beneath the burner structure, a sleeve member positioned axially of the burner structure, a shield member positioned beneath the burner structure and around a portion of the generating apparatus, and a single bolt extending through said burner structure and said sleeve and through an aperture in the bottom of the shield member for holding said parts in assembled relation, said shield structure being completely independent of the means for supporting the burner structure above the fuel tank and being removable independently of said supporting means.

7 A fire pot of the liquid fuel type, comprising an annular burner structure supported above the fuel tank, the inner wall of said annular burner being provided with an annular slot, a perforate burner member positioned adjacent said inner wall and said slot, a deflector member having a centrally raised portion, and an outer annular portion registering with said slot of the burner, said outer annular portion also positioning said perforate burner member in place, and a single means passing centrally through said deflector member and through a portion of the burner for holding said parts in assembled position.
